VULOANIZIN Application filed May 2 This invention relates to a vulcanizing apparatus by means of which repairs of tires, protecting covers and the like can be rapidly and perfectly made.

The invention is characterized in that with a heating vessel, of for instance rectangular cross section, all apparatus and auxiliary means are connected which are necessary for vulcanization 50 that the transportable apparatus canv be placed on any convenient source of heat or may be fitted with such a source of heat.

Two embodiments of the invention are shown, by way of example, in the according drawing in which Fig. 1 shows in side elevation an apparatus of preferred construction.

. Fig. 2 is a planview of Fig. 1.

Fig. 3 shows in side elevation an apparatus of modified construction.

Fig. 4 is a plan view of Fig. 3.

A small sized heating vessel a, preferably of rectangular shape (Figs. 1 and 2) and made from cast steel, has at the rear side a lug b in which a bearing bracket, composed oftwoparts, is pivotally fixed, the arm 0 of which carries a a hand wheel 6. The front arm 7 ofthe bracket is hingedly mounted at-g on an arm 0 and forms at its end a hook it. Arm 7' forms a latch bar, whose hooked end it is engageable under a rigidlatch lug 2' on the front side ofthe vessel a, whereby the arm 0 is held fixed and against movement when the member d is in use to clamp an object. Upon swinging arm 7 outwardly the arm 0 is free to be moved on its pivotal connection, as will be readily understood. A tubular inlet is is mounted on the rear side of the vessel laterally of the arm 0 of the bracket. The tubular outflow Z-may be mounted on the right or left side of vessel (1.

The rear corner of the vessel 0 is bevelled and on it a safety valve m is mounted by means of a tube n on the upper portion of the wall of the vessel, a tube 0 of a manometer p being fixed on the lower portion of this bevelled part.

In the second form of construction of the apparatus, shown in Figs. 3 and 4 the heating vessel a is somewhat widen It has, latpressure screw d having I G APPARATUS.

erally of the middle line of the rear wall, two lugs b in which the bearing brackets 0 for the pressure spindles d, e are rotatably mounted. The bearing brackets a are hingedly connected, in a similar manner as in Figs. 1 and 2, with an arm fig, k.

The tubular inflow k is arranged between the lugs 6. Z is the tubular outflow. The safety valve m is mounted on the top'plato of the heating vessel between the pressing spindles. The manometer p is situated at the side of the tubular inflow the tube 0 of the manometer opening into the lower por tion of the heating vessel.

The vessel on has, as shown in Fig. 3, feet 9 designed to carry the heating device.

The apparatus might also be placed on any convenient source of heat, gas cooker, spirit oven or kitchen range. A source of heat of any convenient type might further be permanently connected with the apparatus.

The apparatus is ready for use, easy to manipulate and constructed in such a manner that burning of the works, whether they are of small size or of large size is excluded.

I claim 1. A vulcanizing apparatus comprising a heating vessel of rectangular form and having a top plate, a pivot lug at the rear side ofsaid vessel, an arm having an upright portion journaled at its lower end in said pivot lug and a horizontal portion rigid with said uprightportion and overhanging the top plate of the vessel, said horizontal portion of the arm terminating at its free end substantially in alinement with the front side of the vessel, a clamping screw carried by said horizontal portion of the arm for coaction with said top plate, and a releasable latch connection between the front side of the vessel and the overhanging free end of the horizontal portion of said arm.

2. A vulcanizing apparatus comprising a heating chamber of rectangular formation and having a top plate, a pivot lug at the tion, said horizontal portion extending above upper end to the free end of the horizontal the top plate of the chamber and terminatportion of the arm and having a hooked ing at its free end substantially in alinement lower end adapted to engage under the latch l with the front side of said chamber, a lug at the front side of the Vessel.

clamping screw carried by said horizontal In testimony whereof I aflix my signature. portion of the arm for coaotion with the top plate, and a latch member pivoted at its JOSEF ZANGL.
